| X5070 To RHC.{R. H. Coverley - Production Engineer} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}5/KT.16.5.31. 25 HP. INDUCTION PIPE. Will you please make an induction pipe for the latest Zenith carburetter, type 35 D.U.P. Attached is a scheme which we think has all the necessary information except the following - (1) Flanges to the cylinder block. These are the same as those shewn on sch.1201. (2) Flanges for the carburetter are slightly different to any previously made, and we hand you herewith the carburetter to work to. (3) The scheme shows the hot spot taken through the cylinder block. Actually the hot spot should be carried to the cylinder head. We are urgently requiring this pipe in connection with our increased power output test and should therefore be obliged if you would let us have it as soon as possible.
